Ton/Z1 whom it may concern.-

Be it knownthat I, HARVEY W. Looxn, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Im rovements in- Cameras;

and I do hereby dec are the following to be a 1 mit the hol er tosupport the sensitlzed material in the focal plane at any desired position of angular adjustment.

My-invention has for its further object to provide a simple and com act arrangement of the parts connecting the ack or closure to a the casing, whereby the usual a pearance of the camera is not altered, and w 10h will permit the back to be readily removed when desired.

To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings, Figure 1 is a longitudinally-sectional view of a camera, showing the arts in the extended or operative. position. Fig. 2 is a erspective view of the rear of the camera, s owing the back or closure detached. Fig. 2 is a rear elevation. Fig. 3 is a similar view illustrating the rotary movement of the camera-back. Fi 4 is a sectional view on the line 4: 4 of ig. 3. Fig. 5 is a rear elevation of the camera-casing with the back or closure removed, and Fig. 6 is a view of the inner inside of the camera'- back removed from the casing. Fig. 7 is an enlarged sectional view on the line-7 7 X of Fig. 2. Fi 8 is a detail sectional-view illustrating t e lockin device, Fig. 9 is a sectional view on the ine 9 9 of Fig. 2,

and 10 is a sectional view on the line 10*- 1 0 of g. 9.

Similar reference-numerals in the several figures mdloate slrmlar parts.

In illustrating my invention I haveshown it applied to the usual form of folding camera consisting of the hollow rectan ular body or casing 1, open at its forward side and having hinged at one edge a bed or extension 2, on

which is adjustably mounted the support 3, carrying the lens 4 and between which and 'the mner partition or wall 5 of the casing extends the ght-exoluding bellows 6, the aforementioned parts being collapsible and adapt ed to be contained wlthin the casing 1 when not in use and protected from injury by the front 2, which 1s secured in position to close the front of the casing by a spring-latch 7, as will be understood.

In the present embodiment of my invention the rear wall or partition 5 is located slightly within the rear edge of the casing 1, formin therein a shallow rectangular recess 8, as s own particularly in Figs. 1 and 4'. Also provided in the rear side of the casing is a circular recess 9, which is made slightly" is a so larger in diameter than the latter, so that portions of the sides of the rectangular aperture are removed, as indicated at 10 in- -Fig. 5. Into this circular aperture extends a hub 15, projecting from the inner side of the back or closure 16 and which is provided with a track, preferably formed by two segmental plates 17 and 18', attached thereto by screws. 19 and having their edges 'extend'in" over an annular channel or groove 20, forme on the hub. Engaging over the edges-of thetrack-plate are securing members in the form of triangular plates 21, which are secured to the wall 5 of the casing by screws 22, their deeper than the rectangular aperture 8 and inner edgesbeing curved and projecting into the circular recesses, as shown in Fig. 5, and adapted to engage the wall of the recess or channel 20 to form a bearing for the hub.

While the track on theback or closure may be in the form of a complete circle or ring, prefer to construct it ofthe two se plates 17 and 18, arranged at opposite sides of the hub 15, each of which is of-sufiicient e ta IOO

length'to engage two of the securing members or plates 21 when the closure orback is in its normal posit on on the casing, as illus-. trated in dotted lines inFig. 5, as..-fihflfs\ ar rangement permits the track to be disengaged from the securing members or plates located at'diagonal corners of the casing when the back is given a partial rotation, as will be understood from an inspection of Fig. 3. When the back is rotated into the position shown in Fig. 3, the several cornerplates are visible, and the late or securin member 21 being provide with elongate apertures through which its securing-screws pass may be retracted against the tension of the spring 25 to disengage it from one of the tracklates, permitting the back to be detache and removed from the casing by a slight lateral movement sufficient to disenigrage the oppositely-arranged track-plate om the plate or member 21.

The back or closure is provided with the central rectangular aperture 26, the limits of which are prescribed by the circular hub, and as the aperture is somewhat smaller than it would otherwise be in a camera of corresponding size the walls of the aperture are beveled outwardly, as shown, at such an angle that the sides extend substantially parallel to the rays of light emerging from the lens, thus enlarging the focal plane ofthe camera. This feature permits the back or closure to be attached in the manner described to the standard sizes of cameras without increasing the size of the casing or decreasing the area of tne focal plane. The aperture is normally closed at its outer side by a relatively movable cover 27, mounted upon the supporting-arms 28, adapted to permit its outward movement and allow a photographic-plate holder to be inserted and secured in alinement with the aperture 26, as will be understood. Also arranged in the cover is a door 29, supported at one side by hinges 30 and normally held in closed position over the interiorly-arranged groundglass focusing-screen 31 by means of a springlatch 32. In order to secure the cameraback in its various positions of adjustment,

.-- so that an exposure may be made upon a photographic late or other sensitized material'with the onger' axis thereof extending either horizontally or vertically, a latch device is mounted upon the casing 1, consisting pin or bolt 33, which is normally projecte beyond the rear edge of the casing by a spring 34 and adapted to automatically engage with one of a series of apertures 35, provi ed in the inner face of the camera-back 16. The bolt 33 is provided with a button or head 36, by means of which it may be retracted, and in locating the latch in the casing it is arranged in such a osition that when the bolt is in a retracte osition and the camera-back revolved the ace of the latter will overlie it and hold it in the inoperative position until one of the apertures registers therewith, when the spring 34 will cause it to be projected to lock the parts.

While I have illustrated my invention as applied to a camera adapte to receive a plate-holder, it will be understood that the invention may also be embodied into parts employed for attaching a roll-holder or other device and the arrangement of the parts whereby such attachments may be readily disconnected enables an operator to employ a single camera with any form of rlosure or back he may desire to use.
